Is expressive suppression always associated with poorer psychological functioning? A cross-cultural comparison between European Americans and Hong Kong Chinese

The habitual use of expressive suppression as an emotion regulation strategy has been consistently linked to adverse outcomes in a number of domains, including psychological functioning. The present study aimed to uncover whether the suppression-health relationship is dependent on cultural context, given differing cultural norms surrounding the value of suppressing emotional displays. We hypothesized that the negative associations between suppression and psychological functioning seen in European Americans would not be seen among members of East Asian cultures, in which emotional restraint is relatively encouraged over emotional expression. To test this hypothesis, we asked 71 European American students and 100 Chinese students from Hong Kong to report on their use of expressive suppression, life satisfaction, and depressed mood. A moderation analysis revealed that expressive suppression was associated with adverse psychological functioning for European Americans, but not for Chinese participants. These findings highlight the importance of context in understanding the suppression-health relationship.     

New Mandates and Imperatives in the Revised ACA Code of Ethics

The first major revision of the ACA Code of Ethics in a decade occurred in late 2005, with the updated edition containing important new mandates and imperatives. This article provides interviews with members of the Ethics Revision Task Force that flesh out seminal changes in the revised ACA Code of Ethics in the areas of confidentiality, romantic and sexual interactions, dual relationships, end‐of‐life care for terminally ill clients, cultural sensitivity, diagnosis, interventions, practice termination, technology, and deceased clients.     

Working memory and behavioral inhibition in children with attention-deficit/hyperactivity disorder (ADHD): an examination of varied central executive demands,construct overlap,and task impurity

The stop-signal paradigm is the premier metric of behavioral inhibition in contemporary attention-deficit/hyperactivity disorder (ADHD) research. The stop-signal paradigm’s choice-reaction time component, however, arguably places greater demands on working memory processes (e.g., controlled-focused attention) relative to alternative inhibition metrics (i.e., go/no-go (GNG) tasks), and consequently obscures conclusions about inhibition and working memory deficits in affected children. The current study, therefore, aimed to determine whether shared variance between stop-signal behavioral inhibition and working memory performance in children with ADHD reflects overlap between the working memory and inhibition constructs or insufficient specificity of the stop-signal paradigm. Fifty-five children (8–12 years) with and without ADHD were administered established phonological (PH) and visuospatial (VS) working memory measures, as well as stop-signal and GNG tasks that vary with respect to demands on controlled-focused attention. Although working memory and GNG performance each uniquely predicted children’s inattention, stop-signal task performance was not a significant predictor of unique variance in inattention, above and beyond variance associated with working memory. Collectively, these findings suggest that performance on the stop-signal task, compared to the GNG task, is confounded by greater demands associated with working memory and consequently reflects an impure estimate of the inhibition construct.     

Second-order schedules with fixed-ratio components: variation of component size

Key pecking by pigeons was reinforced with food under second-order schedules with fixed-ratio units. A constant total number of key pecks was required for reinforcement under each condition, but the size and, inversely, number of fixed-ratio components were varied. The total response requirement of 256 pecks was divided into fixed-ratio units of 128, 64, 32, 8, and 2 responses. A brief stimulus, which always preceded food reinforcement, was presented upon completion of each fixed-ratio unit. Under most conditions, the pattern of within-unit responding was typical of that under simple fixed-ratio schedules. Overall response rate was an inverted U-shaped function of component size. That is, response rates were highest under moderate sized units (fixed ratio 128 and 64). This relationship is consistent with previous determinations of rate as a function of fixed-ratio value for simple fixed-ratio schedules.     

Religion and Derivative Use: Evidence from the Hedge Fund Industry

We examine how local religions influence derivative usage in the hedge fund industry. Measuring religiosity by the ratio of religious adherents in the county of a U.S. hedge fund headquarters, we find that religiosity is negatively related to the probability of hedge funds using derivatives for speculative purposes. In contrast, funds in regions with higher ratios of Catholics to Protestants are more likely to engage in speculation-based trading of derivatives. Finally, we show that the effects of local religion are more pronounced if the hedge fund size is small. Overall, our study highlights the significant role of local religion in shaping the purpose of hedge fund derivative usage.     

Aversion therapy in two cases of obesity

Two cases of obesity associated with overeating are described in relation to their differing responses to aversion therapy directed at the eating behaviour.     

Use of the frostig DTVP with economically disadvantaged children

This research dealt with the reliability and validity of the DTVP when used with a sample of economically disadvantaged, predominantly Negro children from a large eastern city. Regarding reliability, test-retest and split-half procedures were employed; for validity the test was correlated with intelligence and achievement measures. The authors concluded that (a) the total test values alone evidence the necessary reliability to be used with confidence for diagnostic purposes, and (b) the validity of the measure has not been sufficiently demonstrated.
